Suppose two hosts, A and B, are connected by a 10 Mbps link. The length of a packet is 12 Kb (Kilobits, i.e., 12 × 103 bits). Th

e length of the link is 40 km. Assume that signals propagate at the speed of light (i.e., the ideal speed of 3 × 108 m/s (meters per second)).

Answer:

Answer is provided in the explanation section

Explanation:

Given data:

Bandwidth of link = 10* 106 bps

Length of packet = 12* 103 bits

Distance of link = 40 * 103m

Transmission Speed = 3 * 108 meters per second  

Formulas:

Transmission Delay = data size / bandwidth = (L /B) second

Propagation Delay = distance/transmission speed = d/s

Solution:

Transmission Delay = (12* 103 bits) / (10* 106 bps) = 0.0012 s = 1.2 millisecond

Propagation Delay = (40 * 103 meters)/ (3 * 108mps) = 0.000133 = 0.13 millisecond

Fill in the code to complete the following method for checking whether a string is a palindrome. public static boolean isPalindr
Ilia_Sergeevich [38]

Answer:

(s.charAt(0) != s.charAt(s.length()-1))

Explanation:

public class Palindrome

{

public static void main(String[] args) {

   

    System.out.println(isPalindrome("car"));

    System.out.println(isPalindrome("carac"));

 

}

   public static boolean isPalindrome(String s) {

       if (s.length() <= 1)

           return true;

       else if (s.charAt(0) != s.charAt(s.length()-1))

           return false;

       else

           return isPalindrome(s.substring(1, s.length() - 1));

   }

}

You may see the whole code above with two test scenarios.

The part that needs to be filled is the base case that if the character at position 0 is not equal to the character at the last position in the string, that means the string is not a palindrome. (If this condition meets, it checks for the second and the one before the last position, and keeps checking)

To what extent are surrounded species able to stand the anthropogenic activities?
julsineya [31]

Answer:

At the current rate, surrounded animal species might not be able to stand anthropogenic activities in the nearest future.

Explanation:

<em>Anthropogenic activities are those human activities that causes change in the biophysical environment, ecosystems, biodiversity, and natural resources. It also includes global warming, mass extinction of animals and loss of bio-diversity and other global disasters brought about by human activities</em>.

<em>The main driving force of anthropogenic activities is the pressure brought about by the ever growing human population</em>. The earth is overpopulated by humans, and this pushes man to maximize his environment, even to the detriment of this environment. Animal species are hunted to extinction due to increasing demand for their meat, or ornaments gotten from these animals, or some of their body parts, perceived to hold medicinal power, industrial activities poison the environment and natural resources all around, and some ecology has been destroyed and native species population decimated, just because man felt he had to control his environment, sometimes by introducing foreign species he feels he needs.

If nothing is done to halt the current rate of anthropogenic activities, by controlling human population growth, man might end up occupying the planet all alone by himself with surrounding species utterly destroyed.
